BICYCLE-BELL.

SPECIFICATION forming part of Letters Patent No. 590,659, dated September 28, 189'?.

Application filed January 15,1897. Serial No. 619,365. (No model.)

To @ZZ whom it may concern.

Be it known that we, PAUL FLUCKS, a subject of the Emperor of Germany, and GEORGE P. MCDONNELL,a citizen ofthe United States, residing at St. Louis, State of Missouri, have invented certain new and useful Improvements in Bicycle Alarm-Bells, ofwhich the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming a part hereof.

Our invention has relation to improvements in bicycle alarm-bells; and it consists in the novel arrangement and combination of parts more fully set forth in the specification and pointed out in the claims.

In the drawings, Figure lis an elevation of one side of the device as applied to the wheel. Fig. 2 is an elevationof the opposite side, with the roller, however, disengaged from the tire of the wheel. Fig. 8 is a section on line of Fig. 1. Fig. 4 is a front elevation of the device, the bell being partly broken away. Fig. 5 is a detail view of the controlling-spring for the hammer-lever and the roller-carrying arm, and Fig. 6 is a detail of the roller-carrying arm. l

The present invention is an improvement on the construction of alarm-bell described in United States Letters Patent granted us under date of December 8, 1896, and numbered 572,881, the object being to materially simplify the same in several particulars apparent from a detailed description of the invention, which is as follows:

Referring to the drawings, 1 represents the bell, which7 like in the patented construction above referred to, is secured to the lower fork of the steering-rod by means of an arm 2, the lower end of which terminates in a clamp 3, adapted to be carried by one of the members of the fork. The upper end of the arm is passed over the terminal screwthreaded end of the stem 4, by which the bell is directly carried, a nut 5 serving to secure the parts, and a slot 6 being-formed at the upper end of, the arm 2, whereby any desirable adjustment in the securing of the parts is possible. Also secured to the screwthreaded end of the stein 4 is a bar 7, projecting a suitable distance beyond the Vperipheral edge of the bell, the said projecting end of the bar having secured thereto or formed therewith a (preferably) rectangular or oblongjframe 8, projecting forwardly of the bell and substantially at right angles to the plane of the free peripheral edge o f the bell. Along the inner surface of one of the lateral walls of the frame and at a point adjacent to the upper edge of said wall and in proximity to the outer terminal wall of the frame isrpivjotedra lever 9, whose inner arm is conned within the limits of the frame and whichcarries a hammer 10, adapted to operate upon the bell, and whose outer upwardly-curved arm is provided withan expanded terminal portionhaving a basal outwardly-inclined straight edge 11, for a purpose to be presently described. The lever 9 operates upon the bell by being caused to oscillate in a vertical plane about its pivotal point or fulcrum, being guided in its oscillations by the walls of 'a slit 12, formed in the outer terminal wall of the frame S. Pivoted along the inner surface of the opposite lateral wall of the frame, near the lower edge thereofv and adjacent to the Vinner terminal wall of the frame, is a roller-carrying arm 13, the free outer projecting end of which carries a contact-roller 14, normally bearing against the tire 15 of the front wheel of the bicycle. The side of the roller adjacent to the hammer-lever 9 is provided with a pin 16, which, as the roller revolves in thedirection indicated by the arrowsv in Fig. 1, intermittently ridesver the straight edge 11 of the enlarged end of the curvedarin of the lever 9, raising said end and depressing the inner end carrying the hammer, thus tilting the hammer out of contact with the bell. After the pin 16 has passed off the edge 11 the hammer is again returned suddenly against the bell by a spring, the construction of which we shall now proceed to describe.

Projecting from the inner surfaceof the hammer-lever 9 at a point 'adjacent 'to the pivotal point of said lever and between said pivotal point and the hammer 10 is a pin 17, over which is coiled the terminal loop 18 of a spring-arm 19, forming the continuation of a medial resilient spring-coil 20, formed at the juncture of said arm 19 and a second arm 21, terminating in a loop 22. The latter is coiled about a pin 23, projecting from the inner surface of the roller-carrying arm 13 at a point IOO adjacent the outer terminal wall of the frame S. The resiliency or tension of the middle coil 2O tends to keep the arms 19 and 21 separated, as best seen in Fig. 5, by which tendency the arm 19 keeps the hammer 10 against the bell, and the edge 11 of the hammer-lever is kept in the path of the pin 16, carried by the side of the roller 14, and the arm 2l tends to keep the roller 14: normally in contact with the tire of the Wheel. The arms 19 and 21 and the basal coil 2O thus form a single spring whose arms simultaneously control the rollercarrying arm and the hammer-lever.

The operation now becomes apparent. As the tire 15 revolves, as indicated by the arlrow, the roller 14 will revolve, as indicated,

the pin 1G thereof with each revolution riding over the inclined edge 11, tripping the hammer-lever against thev resiliency of the spring-arm 19 and coil 20, the latter in turn bringing the hammer forcibly against the bell the moment the pin 16 has passed off the edge 11, and so on indefinitely, the bell ringing all the time that the machine is in motion. (ln the other hand, the roller la is kept normally in engagement with the tire by the resiliency of the coil 20 and arm 2l, the direction of action of the said arms being indicated by the arrows in Fig. 5. To disengage the roller from the tire, we provide a disengaging-lever 25, the same being pivoted along the outside of the lateral wall of the frame carrying the roller-carrying arm and at a point near the outer terminal wall ot' the frame 8, the said lever being provided with an elongated slot 26, through which passes the lateral outwardlyprojecting pin 27, carried by the arm 13, the free end of the disengaging-lever being connected to the lower end of a cord 2S, whose opposite end can be controlled or pulled by the rider in any mechanical manner-such, for example, as the arrangement shown by the construction described in the Letters Patent above referred to. The pin 27 projects from a lug 29, forming part of the arm 13, this arrangement being resorted to to enable the pin 27 to rest at the base of a concave depression 30, formed in the adjacent side wall of the frame, when the free end of the arm 13 is in its lowest position*that is, When the roller 14 is in engagement with the tire of the wheel. As the free end of the disengaginglever is raised (see Fig. 2) by the cord 28 to release the roller the connecting-pin 27 is free to slide Within the limits of the slot 26 of said lever. In its movements the forward end of the arm 13 is guided by the Walls of the slit 31 cut for its reception in the outer terminal wall of the frame S.

.It is apparent that the construction might be varied in a few details Without departing from the spirit of our invention.

Having described our invention, what we claim is- 1.
